[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 , the utility model provides a technical solution:

[0024] A water treatment filter, comprising: a main body; the main body comprises a first filter box 1, a second filter box 2 and a third filter box 3 arranged in sequence, a water inlet pipe 4 is arranged on one side of the first filter box 1, a water outlet pipe 6 is arranged on one side of the third filter box 3, the second filter box 2 is located between the first filter box 1 and the third filter box 3, and the second filter box 2 is connected to the first filter box 1 and the second filter box 2 through a connecting pipe 5;

[0025] Filter assembly: The filter assembly includes a first filter layer 7, a second filter layer 8 and a third filter layer 9. The first filter layer 7 is installed inside the first filter box 1, the second filter layer 8 is installed inside the second filter box 2, and the third filter layer 9 is installed inside the third filter box 3. The first filter layer 7 is set to PP cotton material, the second filter layer 8 is set to porous activated carbon material, and the third filter layer 9 is set to KDF filter element.

[0026] In actual use, water passes through the first filter box 1, the second filter box 2 and the third filter box 3 in turn, and the first filter layer 7, the second filter layer 8 and the third filter layer 9 of different filter materials are respectively arranged in the first filter box 1, the second filter box 2 and the third filter box 3. It is firstly coarsely filtered through PP cotton to allow water to pass through, while intercepting larger impurities, which can effectively remove large particles of impurities, while reducing the burden on subsequent filter layers and extending the service life of the entire filter; then it is adsorbed by porous activated carbon for impurities, which can adsorb organic pollutants and odors in the water and improve the taste of water; finally, it is filtered through a KDF filter element to remove heavy metals and acid ions in the water, improve the activation degree of water, and then discharged through the outlet.

[0027] The device has a simple structure and is easy to use. It adopts a multi-stage filtration design and can effectively remove a variety of pollutants in the water. It has high filtration efficiency and capacity and can provide safe and healthy water after filtration.

[0028] See also Figure 2-3 In order to facilitate the replacement of the first filter layer 7, the second filter layer 8 and the third filter layer 9, the device is designed as follows:

[0029] The tops of the first filter box 1, the second filter box 2 and the third filter box 3 are all mounted with a box cover 12 by fixing screws, and fixing plates 15 are arranged on both sides of the upper ends of the first filter box 1, the second filter box 2 and the third filter box 3 and both sides of the lower end of the box cover 12, and the fixing plates 15 are provided with screw holes 16 for installing fixing screws.

[0030] The first filter layer 7, the second filter layer 8 and the third filter layer 9 are each provided with a frame 17 on the outside, and the first filter box 1, the second filter box 2 and the third filter box 3 are each provided with a U-shaped holder 10 on the inner wall. The frames 17 on the outside of the first filter layer 7, the second filter layer 8 and the third filter layer 9 are respectively inserted into the slots of the U-shaped holder 10 on the inner wall of the first filter box 1, the second filter box 2 and the third filter box 3.

[0031] By setting a frame 17 on the outside of the first filter layer 7, the second filter layer 8 and the third filter layer 9 and connecting the box cover 12, the frame 17 can be inserted into the inside of the U-shaped holder 10 for fixation when the box cover 12 is installed. When the first filter layer 7, the second filter layer 8 and the third filter layer 9 need to be replaced, the box cover 12 can be removed and the frame 17 can be pulled out, which greatly improves the convenience of using the device.

[0032] See also Figure 2-4 In order to make the connection between the frame 17 of the first filter layer 7, the second filter layer 8 and the third filter layer 9 and the U-shaped card seat 10 more tightly, the device is designed as follows:

[0033] The top of the frame 17 outside the first filter layer 7, the second filter layer 8 and the third filter layer 9 is provided with a top plate 11, and two groups of connecting rods 13 are symmetrically provided on the top of the top plate 11. The connecting rod 13 is slidably inserted into the box cover 12, and the end of the connecting rod 13 passes through the box cover 12 and is connected to the limit block 14. A compression spring 18 is sleeved on the connecting rod 13, and the upper end of the compression spring 18 abuts against the inner top of the box cover 12, and the lower end of the compression spring 18 abuts against the surface of the top plate 11.

[0034] When installing the box cover 12, the frame is inserted into the U-shaped holder 10. At this time, the compression spring 18 exerts a downward pressure on the top plate 11, so that the frame can fit firmly with the U-shaped holder 10. When filtering water, it can prevent the filter layer from loosening easily, thereby improving the stability of the equipment during use.

[0035] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
